Be it known that I, NIMROD W. L. BR WN, a citizen of the United States residing at Marietta, in the county of Cobb and State of Georgia, have invented new and useful Improvements in Oil-Press Boxes, of which the following is a specification.

The present invention relates to presses, particularly to such presses as are designed for expressing fluid from. oleaginous substances, such as cottonseed, flaxseed and the like, wherein a plurality of press boxes are employed within which the oleaginous matter is compressed, and from which boxes, after pressing, the cakes must be removed.

The object of the present invention is clesigned to facilitate the removal of the oil cake, which, owing to the pressure employed for extracting the fluid substances therefrom, is tightly packed. .withinthe press boxes and so far as known canbe removed only by the use of suitable tools inserted between the cake and the box forcprying the cake loose.

The present invention consists of a tool seated. in the main interior pressing surface of the oil press box and adapted to be moved into the box for the purpose of forcing the cake in part or in whole from the box.

In order that the invention may be fully understood, by those skilled in the art, at-

tention is directed to the accompanying drawing illustrative of one embodiment of the invention in which Figure 1 is a plan V16? in outline of an oil press box having the invention applied thereto. Fig. 2 is an end elevation of a portion thereof. Fig. 3 is a sectional view on the line 83 of Fig. 1. Fig. 4: is a view similar to Fig. 2 with the plug closure or loosening tool removed to show the window or opening in which it is seated. p

In the drawings, wherein like reference characters are used to indicate the same parts in all the figures, 10 indicates a press box having a marginal wall 11 around its four sides which, as here shown, is of rectangular shape. At one end of the press box the wall 11 is pierced by one or more openings or windows 12, preferably near the corner of the box. On each side of said opening is a projecting lug 13, perforated at 14-, to receive a pivot pin 15 on which a cake loosening tool 16 is hinged, said tool serving also as a plug closure for the opening or window 12. The loosening tool 16 x formed in the main interior pressing surface 19 of the box. The underside of the finger spe ifi i n 1 memes PatentedOct. 20, 1914. Application filed January 7, 1913. Twi No. 740,638.

17 is madeflush with the surface 19, as

shown in Fig. 3. Exterior of the pivot pin 15 the loosening tool 16 is provided With an outwardly projecting stud 20, in which is formed a socket 21 to receive a bar or other implement for rocking the loosening tool.

Constructed as described, the material from which oil is to be expressed is compressed against the surface 19 of the press box and as the pressure applied must be great, said material is compressed into a i cake which adheres very tightly. to the surface 19- and sides of the press box, so that powerful leverage is required to separate the cake from the box: After the cake has been pressed-and the press boxes 10 separated, a bar of suitable length is inserted in the socket 21.0-f the loosening tool and lifted.

This lifting movement depresses the nose 17 of the tool and forces part of the cake laterally or broad face foremost away from the surface 19 and below the edge of the box, the loosening tool being preferably capable of rocking to the position indicated by dotted lines in Fig. 3. 1

After a corner or edge of the cake has been bent down as described, a slicing tool is inserted between the cake and the bottom edge of thebox, and the cake priedaway from the surface 19 in a manner well understood by those skilled in the art. The outer end of the loosening tool 16 is made heavier than the finger 17 to overbalance said finger and return the tool to normal position, re-
